It is unlikely to be nylon simply because it would be a poor choice for a “first print.”
Nylon is highly hygroscopic and needs to be be dried before printing. In some environments it will absorb enough moisture in a day to make it unprintable. It also has a thermal expansion coefficient that is similar to ABS, which makes it more difficult to keep from lifting and warping. And it needs to be printed hotter than ABS.

And not for lack of trying, as I have a whole bucket full of nema 17 and nema 23 stepper motors I collected from junked office printers. Almost every one of them has a press-fit gt2 2mm sprocket. Perhaps if I could slow it down for fine details it might work better but as such, all I get is correctly spaced bumps instead of tooth profiles. I’ve had my friend print me a few gears with one of those Prussia-style printers with much better results, so it is doable. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
